' HASP Filed June 24, 1951 A If i a P Patented Mar. 8, 1932 UNITEDSTATES PATENT OFFICE OSWALD I. GROTTE, OF HUNTER, NORTH DAKOTA HAS]?Application filed June 24,

This invention relates to certain new and useful improvements in haspsand the primary object of this invention is to provide means forretaining the hasp against casual unlatching, and to thereby retain thedoor or closure tightly closed at all times.

In the types of hasps now used, there is always present slight playbetween the hasp plate and the keeper, thus permitting the door to swingslightly ajar creating drafts,

. rendering the use of hasps objectionable.

I overcome the above objection, through an arrangement of parts,embodied in the hasp construction as will be best apparent from a studyof the following description, taken in connection with the accompanyingdrawings wherein:

Figure 1 is an elevational view of a hasp embodying the features of thepresent invention, the same being shown as applied to a door or closure.

Figure 2 is a plan view thereof.

Figure 3 is a perspective view of the hinge plate of the haspconstructed in accordance with the present invention.

With reference more in detail to the drawings, it will be seen that Ihave applied the invention to a conventional type of hasp and one thatis well known in the art. The hasp, as shown, includes the usualattaching or hinge plate 5 to which is hinged at one end as at 6, thehasp plate 7 that at its free end is provided with the usual slot oraperture 8 through which the head 9 of a keeper 10 is passed, so thatwhen the head 9 is subsequently rotated to the position shown in Figure1, the head contacts the outer face of the hasp 7 thus retaining thedoor or closure in a closed position.

In actual practice and as is well known in the art, the plate 5 issuitably secured to the door or closure D, and the attaching plate orbody portion of the hasp is suitably secured to the wall or door jam B.

In the type of hasp shown, the keeper usually is of swivel type topermit the rotation of the head thereof as and for the purpose aboveexplained, and as shown in Figure 2 there is considerable space orclearance between the head 9 and the base plate of the 1931. Serial No.546,633.

keeper thus leaving the free end of the hasp plate 7 free to movebetween the head 9 and the base plate of the keeper so that a gust ofwind acting on the door or closure D causes the same to swing slightlyajar thus permitting draft.

lo overcome this objectionable feature, I propose to provide, preferablyadjacent the free end of the plate 5, a projection 11 transversing theplate and projecting from the plate a sufficient distance to compensatefor the clearance between the head 9 and the base plate of the keeper aswill be apparent from a study of Figure 2, so that when the head 9 isrotated to the position shown in Figure l, the inward swinging movementof the plate 7 being limited by the projection 11, the head 9 will bindagainst an adjacent portion of the hasp plate 7 with the result, thatthe hasp plate 7 will be effectively held against any swinging movementabout its hinge 6 and consequently the door D will be retained in asecurely closed position.

As shown in Figure .3, the projection 11 is preferably formed byfianging said end of the plate 5, that is, by bending the plate atsubstantially right angles to itself as shown.

Even though I have herein shown and described the preferred embodimentof the invention, it is to be understood that the same is susceptible offurther changes, modifications and improvements coming within the scopeof the appended claim.

Having thus described my what I claim as new is:

A hasp including in combination a hinge plate, a hasp plate hingedthereto, and said hinge plate being provided with a non-yieldingprojection extending laterally therefrom and against which said haspplate abut-s when invention,

the latter is swung into position for engage- OSWALD I. GROTTE.
